Nepalese officials say more than 10,000 Bhutanese refugees were left homeless by a fire that swept through a refugee camp in southeastern Nepal.

Officials say more than 1,300 makeshift homes were destroyed on Saturday night at the Goldhap refugee camp located about 300 kilometers southeast of the capital, Katmandu.

The French news agency reports that four people were seriously injured in the fire, and dozens suffered minor injuries.

It is unclear what sparked the blaze.

More than 100,000 ethnic Nepali refugees from Bhutan have been living in the United Nations-run camp since the early 1990s when Bhutanese authorities launched cultural reforms to maintain the kingdom's dominant Buddhist culture.

The refugees are predominantly Hindu.

Last year, the United States offered to resettle 60,000 of the refugees.
